Flowmeter random error estimation by an analytical variance estimation method: a simple test bed

Description

This paper uses an experimental method to estimate the variance of flowmeter errors (random errors or Type A errors), focusing on problems of detecting defects existing in sensors even with verysmall magnitudes. An inexpensive and simple but accurate test bed is shown, based on the detailed experimental estimation method submitted. Some of the difficulties and shortcomings of this estimation are highlighted and a simulation and a real estimation is given.
